Fig. 9. Fragments of the radicle processes of attachment of some Apiocrinite or Lily-shapedanimal in chalk; see description of Plate LI. Fig. 14. A section of a siliceous nodule; probably the cellular appearance is inorganic: fig. 13,is a magnified section of the cells. Mr. Morris thus defines the generic character of these fossil bodies :— Reticular masses of a more or less compressedglobular, elliptical, or polygonal form; rugose and sometimes papillose; connected by minute tubnli or fibriUse. Dendritical,dichotomous, or irregularly aggregated. Clionites Conyheari is characterized by Cells irregular, somewhat polygonal,with one or more papillje; surface finely tuberculated, connecting threads numerous. Note from Mr. Morris, April, 1850. The fossils, however, do not appear to be the silicified sponge (Cliona) by which the ravages in the shell have beeneffected; they are merely casts of the cavities FOSSIL FAUNA. 101 PLATE XLI. A SiLICIFIED CUP-SHAPED SpONGE, FROM ToURAtNE. (Ckenendopora Parkinsoni, of Townsendi, of Mantell.) This beautiful plate of a petrified zoophyte allied to the Spongia, formed the frontispieceto Mr. Parkinsons second volume. The fossil delineated is from Touraine in France, andis one of the most perfect examples of this kind hitherto observed. It belongs to a groupof cup-shaped Amorphozoa, (as these organisms are now named by naturalists, from the greatirregularity of shape which they assume,) termed Ckenendopora. The original organic substanceis transmuted into silex, and the interstices are filled up with carbonate of lime. The samespecies occurs in the greensand in the Yale of Pewsey in Wiltshire, and, I believe, also in thewhite-chalk; for many cyathiform flint
